Common ISO 14001 Audit Nonconformities and How to Prevent Them

16 min read

ISO 14001 provides a framework for organizations of any size or sector to systematically identify environmental aspects, set objectives, ensure compliance, and continually improve their environmental performance. The standard requires companies to consider the “context” of their organization (internal and external factors, stakeholder needs) and to establish processes for planning, implementation, monitoring, and corrective action. When implemented properly, an ISO 14001 EMS helps reduce waste, conserve resources, prevent pollution, and meet legal and voluntary obligations.

Auditors look for evidence that the EMS is documented, implemented, and effective. In practice, common audit findings (nonconformities) often arise in key areas like compliance management, risk assessment, and operational controls.

The following sections detail frequent nonconformities found in ISO 14001 audits across industries. For each issue, we explain why it arises, how it can undermine the EMS, and list best practices to prevent it.

1.Inadequate Leadership Commitment and Context Analysis

Why it occurs: Top management engagement is fundamental under ISO 14001. Auditors often find that senior leaders have not clearly defined or communicated the organization’s environmental policy, or have not properly assessed the business context (internal and external issues) and interested parties (stakeholders) relevant to the EMS. For example, companies may neglect to consider supplier impacts, community concerns, or changing regulations when determining their context. This can happen when leaders view the EMS as a checkbox exercise rather than a strategic commitment.

Impact on the EMS: Weak leadership involvement means the EMS lacks direction and resources. Without a clear policy and strategic alignment, employees may not prioritize environmental objectives. If the context and stakeholder needs are not fully understood (e.g. omitting key regulatory changes or community expectations), the EMS may miss critical risks and opportunities. This undermines credibility and can lead to noncompliance or environmental incidents.

Best practices to prevent this nonconformity:

Engage top management: Ensure executives actively participate in the EMS through policy endorsement, providing resources, and setting an example. Include ISO 14001 performance in leadership meetings or performance reviews.
Conduct thorough context analysis: Regularly review internal/external issues (market trends, new technology, climate risks, economic factors) and stakeholder requirements (regulators, customers, community groups). Use tools like SWOT or PESTLE analysis.
Identify interested parties and obligations: Create a list of stakeholders (employees, neighbors, regulators, customers) and determine their relevant environmental expectations. Update this list periodically.
Communicate EMS significance: Have leaders clearly communicate the environmental policy and objectives to all levels of staff, reinforcing why the EMS matters for the organization’s mission.

2. Incomplete Compliance Obligations Tracking

Why it occurs: Many organizations fail to maintain an up-to-date “compliance register” of environmental laws, regulations, permits, and voluntary commitments. This happens because legal requirements change frequently, and smaller companies may lack a formal process to catch those changes. Some assume “we know the rules” and do not document them or do not review obligations after organizational changes (new products or sites).

Impact on the EMS: Without a clear record of compliance obligations, an organization risks violating laws or missing regulatory deadlines. Auditors will flag any gap as a critical nonconformity. Noncompliance can lead to fines, shutdowns, or reputational damage. It also prevents the EMS from effectively preventing pollution or ensuring responsible operations.

Best practices to prevent this nonconformity:

Maintain a legal register: Document all applicable environmental laws, regulations, and other requirements (permits, industry standards). Include details like citation, requirements, and affected operations.
Regularly update the register: Assign responsibility (e.g. a compliance officer or team) to review and update the register on a schedule (e.g. quarterly) or when notified of legislative changes. Subscribe to government bulletins or legal update services for alerts.
Assign clear responsibilities: Clearly designate who is responsible for tracking and communicating changes in obligations (legal, sector-specific, or customer requirements).
Integrate compliance in EMS processes: Include compliance checks in internal audits and management review. For example, verify that all new permits or regulations are reflected in the compliance register and that implementation measures are in place.
Use tools or software: Consider compliance management software or checklists to map regulations to site operations and track corrective actions if gaps are found.

3. Incomplete Environmental Aspects and Risk Assessments

Why it occurs: ISO 14001 requires identifying all ways the organization interacts with the environment (environmental aspects) and assessing associated risks or impacts. Auditors commonly find that companies only list obvious aspects (like waste generation or air emissions) but overlook indirect or indirect impacts (like supply-chain impacts, office waste, water usage). Risk assessment is often superficial or omitted. Smaller businesses may lack expertise to conduct thorough assessments, or they may only update aspects when incidents happen.

Impact on the EMS: If significant aspects and risks are missed, the EMS cannot effectively control the most important environmental impacts. This can lead to uncontrolled pollution, resource waste, or missed opportunities for improvement. For example, if a chemical spill hazard is not identified, there will be no controls in place to prevent or respond to it. This undermines one of ISO 14001’s main purposes – proactive risk management.

Best practices to prevent this nonconformity:

Use a systematic identification process: Assemble a cross-functional team (operations, maintenance, safety, procurement) to brainstorm all activities, products, and services that interact with the environment. Do this for all areas of the business, including auxiliary services (e.g. cafeterias, transport).
Consider the full life cycle: Analyze inputs and outputs at each stage (raw material sourcing, production, use, disposal) to catch upstream and downstream aspects. For example, consider the impact of purchased components or how products are disposed of.
Evaluate significance: Once aspects are identified, assess them using criteria (severity of impact, likelihood, frequency). Document the risk assessment method and ensure it’s applied consistently. Prioritize highest risks (those needing immediate controls).
Incorporate changes promptly: Update the aspect register whenever processes change (new equipment, new chemicals, expanded facilities) or when new regulations appear. Don’t rely solely on annual reviews; assign responsibility to review aspects after any process change.
Engage employees: Encourage employees at all levels to report new potential aspects or hazards. Field workers often know of issues that managers might miss.

4. Unclear or Unmeasurable Environmental Objectives

Why it occurs: ISO 14001 requires setting environmental objectives and targets based on the identified aspects and compliance obligations. A common audit finding is that objectives are too vague or not measurable. For example, an objective like “reduce waste” without a percentage or baseline provides no way to measure success. Often objectives are set casually or copied from other companies without linking them to real data.

Impact on the EMS: If objectives are not specific and measurable, the organization cannot determine if it has improved. Ambiguous objectives make it easy to tick a checkbox without actual progress. This stalls continuous improvement and leaves the EMS directionless. Auditors will note if objectives don’t tie back to significant aspects or if there’s no way to track progress.

Best practices to prevent this nonconformity:

Set SMART objectives: For each significant aspect, define Specific, Measurable, Achievable, Relevant, and Time-bound targets. E.g. “Reduce total hazardous waste by 15% by the end of 2025” is better than “reduce waste”.
Use baseline data: Collect current performance data (past emissions, waste volumes, energy use) to set realistic targets and measure improvement. Document the baseline and methodology for clarity.
Break down objectives: If the organization is large, set site-specific or department-specific targets aligned with the overall goal. This ensures objectives are relevant to each area.
Assign ownership: Clearly assign responsibility and resources for achieving each objective. Often appoint a coordinator or team to monitor progress.
Monitor progress regularly: Include objective performance in routine meetings. Update the status of each objective in management review, and adjust if targets are not on track.

5. Inadequate Operational Controls and Documentation

Why it occurs: Operational controls are procedures and practices that keep environmental impacts in check during daily activities. Auditors often find that companies either lack documented procedures for important operations (e.g. spill response, waste handling, equipment maintenance) or that existing procedures are outdated or not followed. This can happen when organizations rely on informal practices (“that’s the way we’ve always done it”), fail to update instructions after process changes, or underestimate the need to document routine tasks.

Impact on the EMS: Without clear operational controls, employees may be inconsistent in how they manage risks. For example, if there is no procedure for handling a chemical spill, a spill could be managed poorly, causing environmental damage and safety hazards. Auditors will raise a nonconformity if controls are missing or if they are documented but not implemented. This can lead to incidents, regulatory violations, or inefficient use of resources.

Best practices to prevent this nonconformity:

Develop clear procedures: For each significant aspect and associated process, write standard operating procedures (SOPs) or instructions that embed environmental controls. For example, include steps to minimize spills, reuse or recycle materials, or shut off emissions sources.
Document emergency and routine controls: Ensure you have procedures for emergency preparedness (spills, fire, power loss) and for routine activities (preventive maintenance, equipment calibration, waste disposal).
Maintain change control: When processes, equipment, or materials change, update the relevant procedures immediately. Use a formal change management process so that new practices are documented before changes are implemented.
Provide accessible documentation: Keep procedures available at the point of use (digital or printed) so employees can easily follow them. Use clear formatting and language.
Verify implementation: Conduct regular site inspections and walkthroughs to confirm that controls are in place (e.g. spill kits stocked, waste bins properly labeled). Use internal audits to check both the existence and usage of procedures.

6. Insufficient Monitoring and Measurement Procedures

Why it occurs: ISO 14001 requires organizations to monitor key environmental parameters (like emissions, waste, resource use) and evaluate performance against objectives. Auditors frequently observe that companies have not established a formal monitoring plan or have incomplete data. For instance, they may ignore certain emissions, forget to calibrate measurement equipment, or fail to record monitoring results. Sometimes companies don’t define what to measure or leave monitoring to chance.

Impact on the EMS: Without adequate monitoring, the organization cannot demonstrate it is controlling its impacts or progressing toward objectives. It may also miss warning signs of regulatory breaches (e.g. a wastewater parameter exceeding limits). This undermines the “Check” part of the Plan-Do-Check-Act cycle, making the EMS ineffective. Auditors will flag missing data, outdated equipment, or lack of analysis as nonconformities.

Best practices to prevent this nonconformity:

Define what to monitor: Based on your significant aspects and objectives, identify specific indicators (water usage, energy consumption, emissions levels, waste quantities, etc.) to track. Include any parameters required by permits or laws.
Establish a monitoring schedule: For each indicator, specify how often and by what method it will be measured (continuous sensors, weekly meter readings, quarterly lab tests, etc.). Assign responsibility for data collection.
Ensure equipment accuracy: Calibrate and maintain all monitoring equipment (meters, gauges, sampling devices) according to a documented schedule. Keep calibration records as evidence.
Record and analyze data: Maintain up-to-date records of monitoring results. Use spreadsheets or software to trend the data over time. Compare results against targets and trigger corrective action if deviations occur.
Report findings: Review monitoring data in internal audits and management review to verify that operations are within planned limits. Use charts or dashboards to make trends clear to decision-makers.

7. Poor Competence, Training, and Awareness

Why it occurs: An effective EMS relies on people who understand and carry out environmental requirements. Auditors often note that personnel are not aware of the EMS or relevant procedures, or that records of training are incomplete. This can result from treating the EMS as an “official document” without connecting it to everyday work. Some organizations forget to train new staff, or they lack a system to identify training needs related to environmental tasks.

Impact on the EMS: If employees don’t know their roles or don’t understand the environmental impacts of their work, procedures may be ignored. For example, workers might dispose of waste improperly simply because they weren’t trained in the correct process. Lack of awareness also leads to missed opportunities for improvement suggestions from staff who are not encouraged to observe environmental issues.

Best practices to prevent this nonconformity:

Identify required competences: Determine what knowledge and skills are needed for EMS roles (e.g. anyone handling chemicals needs spill response training). Maintain a competence matrix linked to job descriptions.
Provide regular training: Conduct environmental awareness training for all staff and role-specific training (e.g. equipment operators, emergency responders). Document attendance and contents. Include ISO 14001 training when the EMS is updated.
Keep training records: Store proof of training (sign-in sheets, certificates) as part of your EMS records. Auditors will check these to verify that training was delivered.
Communicate the EMS: Raise general awareness by posting the environmental policy, objectives, and key performance indicators in common areas or intranet. Explain why the EMS exists and how each person contributes.
Evaluate understanding: After training, test or observe employees to ensure they understand critical procedures. Address any gaps with refresher training or additional coaching.

8. Inadequate Internal Audits and Management Review

Why it occurs: Auditors frequently find that internal audits of the EMS are either not being conducted as scheduled or are superficial. Likewise, management reviews may be incomplete or missing required inputs. This often happens when companies underestimate the effort needed: audits are pushed to the back-burner or done only when an external audit is imminent, and management reviews are treated as perfunctory meetings.

Impact on the EMS: Without robust internal audits, nonconformities and weaknesses go undetected until external auditors find them. If management reviews fail to include key data (performance metrics, nonconformities, legal updates), leadership cannot make informed decisions. This stifles continual improvement and can allow small issues to become systemic problems.

Best practices to prevent this nonconformity:

Plan the audit program: Develop an audit schedule that covers all elements of ISO 14001 (including all sites and processes) at planned intervals. Prioritize higher-risk areas more frequently.
Ensure auditor competence: Use qualified auditors who are independent of the activities they audit. Provide auditor training on ISO 14001 requirements.
Perform audits systematically: Each audit should have a defined objective, scope, and criteria. Use checklists based on the EMS manual or procedures. Review both documentation and on-the-ground implementation.
Record and act on findings: Document all nonconformities or observations, assign corrective actions with deadlines, and track their completion. Verify the effectiveness of corrective actions in follow-up audits.
Conduct thorough management reviews: Schedule reviews at defined intervals (at least annually) with senior management. Include all required inputs: audit results, objective status, nonconformities, customer feedback, legal changes, resources needed. Use a formal agenda and record minutes, decisions, and action items.
Follow up on decisions: Ensure that management review outputs (e.g. decisions on objectives, resource needs, policy changes) are implemented and communicated. Assign responsibility for each action.

9. Poor Documentation and Record Control

Why it occurs: ISO 14001 mandates control of documented information. Auditors often note when EMS documents (policy, procedures, registers) are outdated, missing versions, or scattered. Similarly, records (training logs, monitoring data, audit reports) may be incomplete or unarchived. This usually happens in growing organizations where document control processes are informal or nonexistent, and people resort to uncontrolled copies.

Impact on the EMS: Lack of controlled documentation makes it hard to demonstrate that processes are defined and followed. Auditors may not find evidence to confirm the EMS is being implemented. Employees may follow outdated practices if they don’t have the latest documents. This can lead to inconsistency and noncompliance.

Best practices to prevent this nonconformity:

Implement a document control procedure: Define how documents are created, approved, issued, reviewed, revised, and obsolete documents removed. Use a numbering or version system. Assign one person or department to manage documents.
Use a centralized repository: Store all EMS documents (policy, manual, procedures, forms) in one place (physical binder or electronic system) so staff know where to find them.
Review documents regularly: Set scheduled reviews (at least annually) to verify documents are current and effective. Update records of approvals.
Control records: Specify retention periods for records (training records, audit reports, monitoring data). Maintain records in organized files. Backup electronic records.
Ensure accessibility: Make sure relevant employees have access to the latest versions. For example, display key procedures or checklists near workstations.

10. Ineffective Corrective Action and Continual Improvement

Why it occurs: Auditors frequently see evidence of recurring issues because past nonconformities were not fully resolved. This happens when organizations issue corrective actions without proper root cause analysis, or when actions are not tracked to completion or evaluated for effectiveness. Some companies close corrective actions prematurely without verifying that the issue is resolved.

Impact on the EMS: Without truly addressing root causes, problems reappear, causing repeated audit findings and undermining trust in the EMS. If corrective actions are not documented or followed up, it suggests that improvement is not happening. This stalls the cycle of continual improvement that is central to ISO 14001.

Best practices to prevent this nonconformity:

Use formal root cause analysis: When a nonconformity occurs, use tools like “5 Whys” or fishbone diagrams to identify underlying causes, not just symptoms. Involve relevant staff in the analysis.
Implement corrective action plans: For each finding, define specific corrective actions, assign a responsible person, and set a deadline. Document this plan.
Track progress and closure: Monitor corrective actions to ensure they are completed on time. Do not close an action item until evidence of implementation is shown. Keep a log of open and closed actions.
Verify effectiveness: After implementing a correction, check that it actually solved the problem (e.g. through follow-up audits or monitoring). Document this verification.
Promote a culture of improvement: Encourage reporting of even minor issues (near-misses, suggestions). Treat corrective action as a positive improvement tool rather than a punitive measure. Share lessons learned across the organization.

By addressing these common nonconformities proactively, organizations can build a stronger, more robust EMS. Regular internal reviews of these areas, combined with ongoing training and leadership commitment, will help ensure smooth ISO 14001 audits and, more importantly, real environmental performance improvements. Keep in mind that minor nonconformities are normal, but the goal is to continuously prevent recurrence and strive for continual improvement in environmental management.
